How do you say this in Classical Arabic language..?

Question

These words.......

"All the world will know your name."

Answer 1

سيعرف [ألّ ث] عالم اسمك

Answer 2

Here is your translation, I wrote it as formally as possible:

كُلّ العالم سَيَعْرفُ اسمَكَ

The way to pronounce it in English phonetics would be, "kull al-'aalam sata'arifu ismaka(if male)/ismaki(if female).

Hope this helps!

Cheers!!
